Fig. 5

The left side of the ordinate lists the feature names, following the naming convention: channel - channel number - biomarker (HbO or HbR) - calculated feature value (average, maximum, minimum, peak, slope, or kurtosis). Darker red denotes higher activity values, while lighter blue represents lower activity values. In the MF group, key brain regions that predicted transfer scores included the frontopolar area (FP), supramarginal gyrus (SMG), dorsolateral prefrontal cortex (DLPFC), and fusiform gyrus (FG).
